실험 절차

In Reaction Scheme 4,6-amino-4-methoxypyrazolo[3,4-d]pyrimidine was converted to the iodo derivative (14) which was treated with 1-chloro-1,2-dideoxy-3,5-di-O-toluoylribofuranose to yield the nucleoside (15). Compound (15) was treated with NaOMe/MeOH to hydrolyze the toluoyl groups and yield the unblocked nucleoside (16). Treatment of (16) with aqueous sodium hydroxide gave (17) which could be converted to the trifluoro-N-prop-2-ynyl acetamide derivative (18). Compound (18) was reduced with hydrogen and a Pd catalyst to yield the trifluoro-N-propylacetamide derivative (19). The 4-amino group of compound (19) was protected by treatment with N,N-dimethylformamide dimethylacetal to give compound (20) which was converted to DMTr derivative (21) and then to the phosphoramidite derivative (22).
